The gravitational force between two objects of masses 2 kg and 3 kg separated by 2 m (G = 6.67×10⁻¹¹) is MCQ with Answer and Explanation

Explanation:
To convert a temperature from Celsius to Kelvin, the formula is K = °C + 273.15. For most physics problems, we use 273. Therefore, K = 25 + 273 = 298 K. Kelvin is the SI unit of temperature, and it never uses a degree symbol.

Explanation:
Candela (cd) is one of the seven SI base units, measures luminous intensity. Lumen is luminous flux (lm = cd·sr). Lux is illuminance (lx = lm/m²). Watt is power.

Explanation:
v_esc = √(2GM/R), independent of m. Heavier object needs more energy, but velocity same. All objects fall at same rate. Important concept.
